Mast 57] ABSTRACT 18 Claims, No Drawings FABRIC FINISHING METHOD AND FABRIC BACKGROUND OF THE INVENTION This invention relates to the treatment of fibrous glass and particularly to the treatment of fibrous glass fabric to improve the esthetic properties and appearance.

Fiber makers have sought to alter the shiny and slippery characteristics of glass fiber fabrics, so that they appear like cotton and wool fabrics. The dyeability of glass fabrics presents a different problem than that presented when dyeing cotton and wool; this is especially true with respect to colorfastness, washfastness, and crocking. Many improvements have been made in these areas in the last decade.

However, when glass fabrics are treated according to the inventive concepts, hereinafter described in greater detail, the fabrics have an appearance that cannot be duplicated in conventional fabrics. Specific reference is made to the fabric's ability, through varying the amounts of filamentary and textured*(*Filamentary yarns are defined herein as a generally parallel arrangement of smooth, multifilament continuous strands lying closely together, that are formed continuously, by mechanical attenuation and gathered upon a collet. Textured yarns have their genesis in filamentary yarns, but are post treated to impart bulkiness thereto. Reference is made to a text entitled Woven Stretch and Textured Fabrics by Berkeley L. Hathorne (1964), p. 9-10, which further defines textured yarns.) yarn and by varying the weave patterns therein, to adsorb varying amounts of pigmented dispersions on the different yarns that make up the fabric and still possess good contrast between the pigmented dispersions.

The effect given to fabrics composed of filamentary and textured glass yarns when treated in accordance with the present invention, is that it appears that the fabrics were woven from yarns of different color and tone, when in fact, the fabrics were woven from undyed yarns. The degree of bulkiness possessed by glass yarns when incorporated into a fabric allows many variations in the degree of color pickup when the fabric is treated with a multiple dye system.

Glass fabrics when treated by the inventive concept show unique utility in the drapery, bedspread, and wearing apparel fields.

It is, therefore, an object of the present invention to provide methods for imparting decorative effects on the surfaces of glass fiber surfaces.

It is another object to produce glass fabrics, composed of filamentary and textured yarns, wherein it appears that the fabrics are woven from multiple colored yarns.

Other objects and advantages will be apparent from the following description.

Our glass fiber fabrics possess an advantage over glass fabrics finished by conventional methods and to fabrics composed of cotton, wool, organics, etc., because we use conventional apparatus such as described in US. Pat. No. 3,065,103 for heat cleaning the glass fabric and for applying resin bonded pigmented finishing systems thereto comprising various colorants, including aqueous dyestuffs and pigment dispersions. Emphasis is made on the fact that in line equipment is used to get the desired effect on glass fabrics.

SUMMARY OF THE INVENTION When the inventive concept is employed on glass fabric composed of filamentary and textured yarn, each yarn therein is capable of adsorbing a specific amount of finish, according to the surface area of the yarn itself. The filamentary yarns of the fabric, after a first padding of finish containing a colorant, appears darker in color than the textured yarns. This effect may be theoretically credited to the fact that in filamentary yarns, the filaments are generally in a tightly packed parallel relationship, so that the amount of dye on all the filaments acts in synergism, whereas in textured yarns, composed of randomly oriented, loosely packed filaments, this effect does not appear. When the fabric is exposed to multiple finish compositions, each having a different color or tone, the textured yarn has the capacity to adsorb more than one finish, depending upon the degree of bulkiness of said yarn, whereas the filamentary yarn is substantially satisfied after adsorbing a single finish composition.

Another possible explanation of why the filamentary yarns exhibit a deeper color than the textured yarns might be due to capillary attraction of the dyestuff to the filaments making up the yarn. This capillary attraction might be stronger than the pressure used to rid excess finish from the fabric, but only in the filamentary yarns, and in effect may hold more of the finish than the textured yarns, thereby substantially satisfying the adsorptive capacities of the filamentary yarns.

The effect of such adsorption capacities of the yarns is that the fabric appears to have been woven from a number of differently colored yarns. Upon close examination of the fabrics, it is observed that the decorative effect imparted thereto is not similar to that of kiss printing or silk screening but, in fact, has a higher quality appearance.

It has been observed that after a first padding of the fabric through a finish containing a first colorant, the filamentary yarns have retained substantially more of the first colorant than the textured yarns. Pressure exerted on the dyed fabric affects the textured yarns much more than it does the filamentary yarns. The textured yarns are resilient and are thereby capable of having more finish expelled therefrom than the filamentary yarns which are substantially rigid in comparison. Since the textured yarn has resiliency imparted thereto because ofits bulky nature, it springs back to its original shape so that those fibers making up the parameters of the diameter of the textured yarn appear white in color or substantially void of the first colorant. This phenomena is analogous to the behavior of a sponge, after squeezing liquid therefrom, wherein the outer portion of the sponge appears lighter in color than the inner portion thereof. However, this phenomena does not occur in the filamentary yarns where the fibers are tightly compacted, thereby imparting to these fibers a deep shade or tone of the first colorant. The textured yarns have a larger available coatable surface area than the filamentary yarns, and therefore have the capacity when passed through a subsequent finish containing a second colorant to adsorb the latter, whereas the filamentary yarns having been substantially satisfied by the first colorant, do not have this capacity to adsorb the second colorant, and consequently the fabric possesses differently colored yarns showing good contrast to provide a novel and decorative effect.

It is preferable to treat the fabric having a first finish dried thereon with a material that prevents the filamentary yarns from adsorbing additional colorant, thereby improving the contrast of color between the filamentary yarns and the textured yarns. Such a material is represented by either l water soluble organo metallic complexes containing from six to 24 carbon atoms such as stearato chromic chloride, laurato chromic chloride, and complexes of aluminum, zirconium and titanium, or (2) aqueous systems of organo silicon compounds in the form of a silane, its hydrolysis products (silanols), or its polymerization product (polysiloxanes), wherein the siloxane has from one to three highly hydrolyzable groups and an organic group attached to the silicon atom containing from one to 18 carbon atoms, as represented by the formula Si X r-i-m wherein X is a highly hydrolyzable group such as chlorine, bromine, iodine or other halogen; methoxy, ethoxy, propoxy or the like short-chained alkoxy group. n is a whole number of from 1-3 and R is a hydrogen group or hydrocarbon radical containing from one to 18 carbon atoms, such as methyl, ethyl, propyl, isopropyl, butyl, pentyl, vinyl, allyl, methallyl, chloromethyl, dichloromethyl, heptyl to octadecyl and the like aliphatic group, an aryl or alkaryl group such as phenyl, tolyl, naphthyl, benzyl, monoand polyalkylphenyls, xylyl, mesityl, mono-, diand tri-ethyl phenyls, methyl naphthyl, diethyl naphthyl, anthracyl, phenyl ethyl and the like, or an alicyclic group such as cyclopentyl, cyclohexyl and the like or a heterocyclic group in which the aforementioned organic groups may be substituted or unsubstituted, saturated or unsaturated.

These materials normally impart hydrophobicity to glass fiber fabrics, thereby explaining why the filamentary yarns refuse to pick up substantial amounts of the second colorant. However, since these materials also contact the textured yarns of the fabric, it is not fully understood why these yarns have the capacity to, and actually do, pick up the second colorant. Whatever the phenomena may be or however further theorized, a high degree of color contrast is provided in the fabric between the first and second colorant, the former being on substantially only the filamentary yarns and the latter being on substantially only the textured yarns that make up the fabric.

It has not been determined whether the second colorant (or third or fourth, as the fabric s needs may require) is mechanically entrapped within the loops and broken filaments that impart bulkiness to the textured yarns, or whether there is chemical bonding between the second colorant and the textured yarns.

Our process comprises the utilization of conventional heat cleaning apparatus and padding apparatus as described in US. Pat. No. 3,065,103 in order to impart colorfastness to glass fabrics. The improvements in the process of this invention lie in the treatment of the fabric after each padding-drying operation, with a stearato chromic chloride solution and controlling the padder pressures on each successive padding operation. Necessary, however, for the attainment of novel decorative effects on glass fiber fabrics is that the fabrics be composed of textured and filamentary yarns.

Generally, during the first padding operation, the fabric is exposed to a higher padder pressure than in subsequent padding operations. The reason for this feature is that it has been found desirable to expel as much of the liquid finish as possible and still substantially fulfill the adsorptive capacity of the filamentary yarns within the fabric, while leaving the textured yarns therein substantially unsatisfied. Subsequently, the already treated fabric after drying, is padded through a padding apparatus having a dip tank containing a solution comprising a stearato chromic chloride complex, and is dried in a conventional multiple pass oven.

It is not known for sure what function this complex provides, but it is thought that it helps to completely satisfy the filamentary yarns while still leaving the textured yarns substantially unsatisfied in their adsorptive capacities.

Subsequent to the above treatments, the fabric is again passed through a differently colored finish solution and passed through the padding apparatus in such a manner that as much finish as is possible is retained by the fabric, i.e., the padder pressure is minimal in order to insure that the textured yarns in the fabric are substantially saturated. Subsequent to drying, the fabric is treated again with a stearato chromic complex and dried to insure colorfastness and washfastness of the fabric.

Where the degree of texturization of the yarns making up the fabric varies, so too does the number of paddings with differently colored resin-pigmented systems. It has been feasible to obtain as many as three to five colors in glass fabrics, with good color contrast, by varying the weave pattern, by using yarns having different degrees of texturization, and by varying padder pressures during the padding operations.

Depending upon the color and tone of pigmented dispersions used in a multiple finishing system, usually the later applied pigments completely mask the earlier applied pigments on the textured yarn, but this is a function of the concentration of the pigments used, and also their color tone.

Any finishing system, such as those that use acrylic resins, may be used when treating fabrics according to the concepts of this invention. Resinous film forming binders are used to bond the colorants to the glass fiber yarns to form color-fast colors.

When a glass fiber fabric is composed of filamentary and textured yarns and is padded through a finish composition comprising a colorant and then dried, the filamentary yarns will have satisfied substantially all of the reactive sites thereon, because the degree of adsorption of the finish decreases rapidly due to the close relationship of the continuous filaments in the filamentary yarns but this is not true of the textured yarn. Consequently, when the fabric is subsequently passed through at least a second finish composition having a different colorant, the textured yarns pick up such a larger percentage of the second colorant than the filamentary yams that in effect the second colorant substantially masks out the first colorant on the textured yarns resulting in a fabric composed of filamentary yarns comprising substantially only the first colorant and textured yarns comprising substantially only the second colorant. Usually, however, neither the first nor the second colorants exist in their true color in the finished fabric because of slight contamination, but this is thought to be an advantage, as long as there is good contrast, because it softens the tones of the fabric.

DESCRIPTION OF PREFERRED EMBODIMENTS The following example is provided as an illustration of the inventive concept, but the invention is capable of other embodiments and of being practiced or carried out in various ways.

EXAMPLE I A glass fabric composed of filamentary and textured yarns was heat cleaned to remove protective sizing, and subsequently padded through a first aqueous finish solution comprising an acrylic film former, a silane, and a first colorant. The padder pressure was established to remove as much finish from the fabric as possible (about 4050 p.s.i.) and then the fabric was dried in a multiple pass oven for 3 minutes at 350 The moisture content of the fabric just after padding and before drying ranged from about 10-20 percent by weight. This percentage was sufficient to substantially saturate the filamentary yarns of the fabric but left the textured yarns therein substantially unsaturated.

The fabric with the first finish dried thereon was then padded through a stearato chromic chloride complex solution, wherein the padder pressure was established to be from about 20-30 p.s.i. The fabric was subsequently dried at 350 F. for 3 minutes. The function of the stearato chromic chloride solu tion has not been definitively characterized, but it is known that upon application of a second finish containing a second colorant, a better contrast of colors results when this complex is first applied to and dried on the fabric.

Thereafter, the fabric having the first finish and stearato chromic chloride dried thereon was padded with a second aqueous finish solution comprising an acrylic film former, a silane and a second colorant, different in color from the first colorant. An important feature herein was the establishment of a padder pressure that allowed as much of the second finish as possible to be adsorbed by the fabric, particularly the textured yarns therein. This padder pressure ranged from about 10-15 p.s.i. Subsequent to the padding, the fabric, with the first and second finishes and a stearato chromic chloride thereon, was dried for 3 minutes at 350 F. in a conventional multiple pass oven.

A high degree of contrast between the colorant of the first finish and the colorant of the second finish was observed on the fabric. The filamentary yarns of the fabric comprised substantially all of the first colorant, and the textured yarns, depending upon the degree of texturization, comprised substantially all of the second colorant. When the degree of texturization of some yarns was not as great as in other yarns, an ancillary benefit resulted because of contamination of the first and second colorants thereon or failure of the second colorant to mask over the first colorant which tended to add a third color tone to the fabric.

The fabric, as treated above, was subsequently padded through a second stearato chromic chloride complex solution at a padder pressure of from about -30 p.s.i. and dried at 350 F. for 3 minutes in a conventional multiple pass oven. This second stearato chromic chloride padding appeared to insure good colorfastness and washfastness to the treated fabric.

Compositions of the first and second finishes used above were as follows:

lgnition loss tests were run on yarns separated from the fabric that was treated as described above. The results were as follows:

Warp Fill Fill Yarn Light Yarn Heavy Yarn Ignition loss I6 2.58 4.l7 5.16

The varying percentages above show that as the yarn con struction varies, the adsorptive properties vary proportionately.

The light fill yarns have a lower end count of filaments than the heavy fill yarns, thereby explaining the difference in ignition loss since the latter, when textured, provides a larger surface area for adsorption. Obvious variations can be made without departing from the spirit and scope of the appended claims.
